I’m thinking of Jet Li’s Hero. It’s totally decent as a movie, but I think it’s almost un-rewatchable. Not because the ending is known, but because of the super long flashback scenes. Many of which focused on long, colourful, extravagant, not really even relevant to the story, scenes.
I think the movie would be much more rewatchable if all that time was spent on

the standoff between Jet Li’s character and the king and things like that.
Id say a big thing for me personally is finding those little details the writers and directors add in that you really only see upon seeing a second, third, or ninth viewing of a film.
Same goes for shows with long overarching stories that have clever details seasons prior.
